4 weeks post op arm liposuction and have no result. Is this normal?

After liposuction, final results can take up to 6 months to be evident. Compression is your friend at this point. This will help to resolve any residual swelling and speed up the resolution of your seroma. Thank you for sharing your photos and concerns. Best wishes.

Thank you for submitting your questions and photo. I am sorry to hear you have a seroma after your procedure.  Your only 4 weeks after surgery.  Swelling
after liposuction will last for many weeks after surgery. 80% of
your final result will be seen in more like 3 months. Final
results take 6-12 months. Continue to use your contour garment, minimize
activities, and lymphatic massage help with the swelling. Continue close follow up and concerns
with your Plastic surgeon.

First, take a big breath.  Contour abnormalities can occur after liposuction.  Seroma formation is less common, but also can occur.  The seroma needs aspiration and compression.  Final liposuction results can take up to a year.  Communicate with your doctor, follow-up as directed, and seek a 2nd opinion if you are not comfortable with the progress of your healing.
